WHEEL AND TIRE.

Specification of Letters Patent.

Application filed September 18. 2911. .Serial No. 649,952.

a citizen of the United States, residing at New York, in the county of New York and State of New Yorln have invented certain new and useful Improvements in Wheels and Tires, of which the following is a speciiication.

My present invention relates to an un- "proved means for securing rubber tires,

especially of the cushion type, to vehicle wheels.

The advantages of my invention will be clear to those skilled in the vart from an understanding of the following description in connection with the drawings. These show one of the forms which my invention is adapted to take, together with a slight modiiication.

Figure 1 is a cross section, partly in elevation, through a tire and portion of a wheel showing a combination within invention, namely, is a section on the line 1-1 in Fig. 2 looking in the direction of the arrows; 2 is a vertical longitudinal section partly in side elevation of the same tire and wheel-portion and is a section on the line in 1 looking in the direction of the arrows; Fig. 3 is a plan view looking down upon the base of the tire after same has been detached from the wheel; Fig. l is a vertical section on the line l-4 in Fig. 1 looking in the direction of the arrows to further illustrate the means for securing the socket-occupying members or blocks to the folly; Fig. 5 is a view similar to Fig. 4: modified to the extent of substituting for the block another form of socket-occupying member; and Fig. 6 is a perspective view on a larger scale of this new form of socketoccupying member.

I will now describe the devices of the drawings, reserving-it to the claims to point out the novel features and to define the scope of the invention, it being understood that the claims will 'be given the due range of equivalents to which they may be entitled in view of the art.

In the drawings, 1 designates the wooden felly of the wheel; 2 is a metal hoop or rim encircling the felly, said hoop having lugs 2 (compare Figs. 2 and 4:) bent up froinit in pairs in longitudinal series around the outside of the'hoop. 3; designates wooden blocks which fit one between'each pair of the lugs They are secured in this position by nails 4' driven through blocks into the felly, said nails passing through the spaces 5 in the hoop (see Fig. 4) originally occupied by the lugs before they were bent up. It will be noted that there are two 1011-. gitudinal series of the aforesaid pairs of lugs and blocks, one series on each half of the felly, and that they are in staggered-- arrangemel." relative to each other.

(S fi are flanges which retain the outer sides of the tire Tat its base. This tire is of the non-pneumatic or cushion type, and the form of its tread and the contour of its sides form no part of the present invention and may vary along with other features of the tire.

8 is a longitudinal opening throughthe tire.

9 is a longitudinal split through the base of the tire leading to the tire opening 8. This word split as used in this specifica 'tion is not to be taken as implying that this Patented Aug. 1'7, 1915..

passage is cut through, since in the preferred actual manufacture of the tire it is formed by a core in the mold, although it might, of course, be formed otherwise. Further, it will be understood that the actual tire will be about twicethe size shown in the draw;

ings. Consequently, the

split 9 is about a half inch wide.

10-40 are clamping portions on the tire. which project inwardly toward each other They the metal hoop 2 to receive the several boltmeans connecting the clamping plates with,

the felly. lVhen the nuts 11 are screwed up, the plates 11 of course clamp the por- --tions 10 of the tire to the wheel.

' 14-I4l designate outwardly projecting beads at the base of the tire which are re ceivedinto the recesses formed for this p'ur a pose in the flanges 6. Free edges 6 of the "n.0-

flanges below the recesses are preferably normally out of contact with the sides 'of the tire as shown in Fig. 1 to diminish the t'angular form and are molded into the base of the tire.

The dotted line 16 in Fig. 1 indicates a layer of canvas molded into the tire flush with its surfaceend l7 designates rolls of canvas molded into the tire to extend lengthwise through the clamping portions 10..

However, both these features are merely de scribed because they are shown in the drawings but are not'here claimed. Describing now the operation of the aforesaiddevices, it will be seen, when the tire is mounted on the wheel as shown in Figs. 1 and 2, that the tire cannot tear loose in any direction. The sockets 15 and blocks 3 being wide are so near at their sides to the clamping means 11 and the flange 6 that constricted necks are formed at the portions of the tire which intervene between the sockets and the clamping means on the one side and the flange on the other. This securely locks the beads 14 and the clamping portions 10 of the tire to the wheel. This construction would weaken the the if 'the depressions 15, instead of being true sockets, continued around the tire in the form of wide channels. This, however, I have guarded against by isolating the depressions and making them true sockets. Furthermore, for the same'reason, v1z: of added strength, I prefer to locate the V sockets 15 in staggered arrangement on the two halves of the tire.

Creeping of the tire is, of course, absolutely prevented by the fact that the lugs 52 and blocks 3 project down into the sockets 15 and receive against them the longitudinal thrust of the tire when same is in motion.

The modification shown in Figs. 5 and 6 consists merely in substituting the blocks 3. by another form of socket-occupying memher 18 consisting of a piece of sheet metal, preferably steel, bent up in the form shown with sharp prongs 18. This memberis shown in use in Fig. 5 and like the block 3 is received between the lugs 2 with its prongs 18 passing through the spaces left in the metal hoop 2 and driven into the wooden telly. 1. These modified members, of course, function precisely like the block 3.

lVhat I claim is:

L'The combination ofa tire having a longitudinal opening through it. with side walls adjacent said opening, said walls at their base having inwardly projecting clamping portions, flanges retaining "the outer sides of the tire at its base, clamping plate means Within the longitudinal opening of the tire, and means for drawing said means to the wheel periphery to clamp the aforesaid inwardly directed clamping portions thereto, each half of the base of the tire having a longitudinalseries of sockets, and the wheel periphery having a longitudinal series of projections corresponding to and fitting into said sockets, the sockets being near enough in transverse direction to the clamping means and to the given flange to form constricted necks at the portions of the tire which intervene between the sockets base of the tire having a longitudinal series of wide sockets, and the wheel periphery having a longitudinal series of members corresponding to and received into said sockets when the tire is in place on the wheel periphery, the sockets in the two halves of the base of the tire having a staggered arrangement relative to each other.

3. The combination of a tire having a longitudinal opening through it with side Walls adjacent said opening, said walls at their base having inwardly projecting clamping portions, each half of the base of the tire having a longitudinal series of sock ets, a felly, a metal hoop encircling the felly having lugs bent up in pairs therefromin longitudinal sequence around the outside of the hoop, socket-occupying members secured one between each pair of lugs, said -members and lugs being located to correspond with and occupy the aforesaid sockets in the base of the tire, flanges retaining the outer sides of the tire at its base, and clamping plate means within the longitudinal opening of the tire, and means for drawing said means to the fellyto clamp the aforesaid inwardly directed clamping portions of the tire to the telly.

4. The combination of a tire having a longitudinal opening through it with side walls adjacent said opening, said walls at' their base having inwardly projecting clamping portions, each half of the base of the tire having a longitudinal series of sock-' ets, a wooden telly, a metal hoop encircling the folly having lugs bent up in pairs therei from in,.longitudinal sequence, around the outside of the hoop, socket-0cm} py-ing mem- 5 to the felly, said means passing through the openings in the metal hoop which were originally occupied by the. lugs before they were bent up, flanges retaining the outer side of the tire at itsbase, clamping plate means within the longitudinal opening of the tire,

and means for drawing said means to the "fe'lly to. clamp the aforesaid inwardly directed clamping portions of the tire to-the felly.

In testimon whereof I aflix my signature 15 in presence 0 two witnesses.
